Temperatures in the low to mid 90s with heat indices possibly approaching as high as 108 today so drink plenty of fluids and take precautions if you work outside. In addition, a large area of Saharan dust continues to remain in place across the Gulf, Caribbean, and the Florida Keys. The dust is expected to gradually move out of the area over the next day or so, which will bring a very small increase in rain chances over the coming days.
